In the following question, a sentence is divided in to

Solution

The correctly matched triplets are AFH, BDG and CEI. AFH: A talks about a time prior to the 24/7 social media and F carries it forward by stating that kids used to spend time on 'online discussion forums' discussing 'shared interests'. H completes this idea by stating that the 'shared interests' included 'films', 'music' or 'sport'. BDG: B talks about 'bank'. Amongst D, E and F, only D can carry the phrase introduced in B forward; the noun 'bank' is carried forward by the verb phrase 'to have to step in'. G carries this idea forward and concludes that it is not a good idea for bank to 'rescue another bank'. CEI: C introduces the water repellent surface of a lotus leaf; 'the fact that a water droplet rolls down its surface. E carries this forward and says that this inspired 'chemical engineers'. Further, E ends with the adjective 'hydrophobic' and must be followed by a noun. I satisfies the grammatical condition mentioned above and carries the idea expressed in C and E forward. Amongst these, only CEI is mentioned in the given options. The other triplets are incorrectly matched. Hence, d) is the correct answer.
